Given the suggestion of using -18-, I decided to calculate how much
bigger our packages would be with the numbers given:

cuda-10.0.130-2-x86_64.pkg.tar			58.5M	104.40%
gcc-8.2.1+20181127-1-x86_64.pkg.tar		2.8M	108.30%
go-2:1.12.1-1-x86_64.pkg.tar			10.6M	108.70%
linux-5.0.3.arch1-1-x86_64.pkg.tar		-0.4M	99.40%
linux-headers-5.0.3.arch1-1-x86_64.pkg.tar	1.9M	111.20%
tensorflow-1.13.1-2-x86_64.pkg.tar		6.2M	111.20%
intellij-idea-community-edition-2:2018.3.5-1	8.1M	102.10%

That is a decent increase.

Are the times given for decompress just a decompress, not install by
pacman?   Were they done on a SSD or pointed at /dev/null? (I assume not
a spinning disk given the times)
